- In this week's how-to home project tutorial I am sharing how I made a DIY grinder vacuum attachment for concrete grinding. While I was grinding concrete my vacuum attachment kept my house from filling with dust. The best part of this floor grinder attachment is it cost me less than $10! Supplies + links below! ⤵

Free, Good Ideas like this make life so much easier. Look at all the leftover parts of things in your house or garage. Look around. Your Invention waits patiently, but not quite like a friendly Labrador Retriever... Thanks Gray House Studio ! You just saved me about 79 dollars.
Haha so true. We are glad to hear you like our unique approach to a grinder vacuum attachment.
Worked fantastic! I used a Cool Whip container with a Diamabrush 4.5 inch concrete grinder for my basement floor prep to paint. When I needed to get right up against the edge of the cement wall, I cut away a section closest to the vacuum inlet. A little dust was getting by but it got the job done without creating a dustbowl. Your video saved me from buying the regular attachment for $60 but most important, I didn't lose time to get the job done. Thanks
Thanks so much for the feedback! It take a surprisingly large amount of effort to slow down enough during projects to film these video and makes it worth it knowing the videos are appreciated!
I use a bag insert on my shop vac. The ones made specifically for drywall dust are a little more expensive but make a world of difference. They keep your filter clean and make emptying the vacuum a lot easier.
Wow. Perfect for my needs. I have a small job and will only use it once.
This worked extremely well, thanks for the great grinder hack!
Great idea. I spent some time and built one like yours. It works excellent to collect the dust. My biggest recommendation is start with a good grinder around 8 amps or more. I used my old dewalt 5 amp grinder and it burned up to soon. Thanks for sharing your design with us👍
So quick and versatile , clever that it sucks down to create a seal, very very well thought out , thank you , waaay better than my diy router effort in fiber glass 😀👍
Thanks for the great idea. I cut down a margarine tub to fit my 4-1/2" Craftsman angle grinder and wrapped the pipe insulation around it like you showed. I have been grinding thinset off the concrete floor in my bath using the modified grinder connected to a shop vac. There is no dust! Before the mod, it instantly created clouds of choking, blinding dust. Yes, I wore goggles and a particle mask but it was far too much dust and it covered everything.
J T thanks for this idea. I just modified a big cottage cheese tub and will be trying it out later today.
Bless you for this! The thought of buying a $150 dust shroud has always driven me nuts, and this is perfect.
You can inexpensive shrouds under 40$ on amazon. I invested in making a dust collector instead and bought the shroud.
Thank you so much for the tip. I cobbled one together and stripped the thinset off my dining room floor this afternoon. I had ceramic tile on plywood but the diamond grinder made short work of the thinset that remained after chiseling off the tile with an air hammer. The dust collector worked GREAT! I had all the materials on had. Cost = $0.00
+Harry M. Thanks for the feedback on the grinder vacuum attachment! It's exciting to hear when inexpensive solutions work for more people than just us.
Thanks for taking the time to publish this video. Your solution works like a charm. I wish there was a dust free solution for the inch of mortar that is left at the jonction of the wall. Removing the cover to finish the job produced so much dust!
+Jean-René Bastien That is great to hear! Ya, I never know what to do in the corner. Have you ever tried using one of those oscillating tools? I bet a dust guard could be made for one of those. I might have to try that next time.
Cut a flat on one side. Or make another one with a flat to cover the junction area. Problem solved. 😄
Great video! I think I would lose the guard, but probably due to liability reasons you included it. Thanks for posting. Cheers.
Thanks brother for the wonderful video. I am working on my floor tomorrow and surely will use some of your skills. Thanks again for sharing.
Glad the grinder vacuum hack is helpful!
This worked so perfectly! Thanks for the idea!
Glad it worked! I still laugh when I see how much dust the grinder without the vacuum attachment created.
That's a great idea, and a nice way to build it. Well done video too - thanks!
+Ski Bike Bee Thanks!
Just made mine.It works perfect!
Awesome! We struggled to find ideas on how to build a vacuum attachment for the grinder and were pumped this worked so well.
Hi. Many thanks for this video.
An idea- Keep the hoover outside.. put the hosepipe through the window if possible..
gr8deals2do why have I never thought of this? Great idea!
Another shout out! This is a very clever idea. Gonna start making mine right away.
You've earned my sub
Thanks! We made this grinder vacuum cover about three years ago and are getting it out again this weekend to work on the floor in another room of our house.
Haha pretty cool grinder hack
Brilliant! Thank you.
Easy and smart. Thanks!
I’m glad to hear you like the inexpensive option.
Great idea! Just what I need for the following days. Might try with a cheap small frisbee, if I can actually find one. (I have a whamoo that I haven't used in years but not up for sacrifice.)
Ya, a frisbee could work well for a vacuum attachment. Don't do anything you will regret!
Skip the Tupperware lid & go for chinses takeout plastic bowl instead. The bowl is perfect size and you don't need the foam. It height is just prefect and sits flush on the ground with the grinder. I cut out half inch diameter rubber hose and stuck inside the hole. Put hose clamp on inside to keep it from popping out the hole. Then duct tape the rubber hose to my vacuum hose.
nice good idea. im a try converting a toilet plunger, see if that works
+mario parra That is a great idea Mario! Our plunger stays in quarantine but they are really cheap. Let us know how your grinder vacuum attachment works out.
Gray, so what happened with the pkunger? Did you ever hear back?
hook it up to a dust collector, the orange home store has one for around 40.00 and the dust will go into the bucket and your vacuum filter will stay clean. Nice work on the shroud!
Ya, I need to invest in a good particle separator. Have you used the one from Home Depot? I am curious if it would work to separate concrete dust and particles from the grinder.
Google home made cyclone dust separator
Run the vacuum hose into a wet-dry vac with an extension hose fitted inside the tank and down to 0.5 inches off the bottom, then put 2 inches of water in the tank making a hookah.
That is a great idea! The water would capture the dust.
This looks very interesting. I just returned one from HF as I was unable to align the HF diamond cutter wheel shroud's bristle bottom edge. Am about to try another manufacturer' sho
(hit the wrong button)...manufacturer's shroud with a diamond disc with an unthreaded arbor hole. If that doesn't work, I will give your solution a try. What the heck! I'll make one of yours while I'm waiting for my order to arrive.😊
LOVE IT!!! Thanks for this :)
brilliant
Thanks! Glad you like the vacuum attachment!
great idea
Doesn't the suction seal make it stick to the floor and difficult to move?
Is the Tupperware made of silicone ?
Great idea but my vacuum creates too much suction. The entire thing sticks to the ground when I turn the vacuum, you end up not being able to move the grinder. I might have to make some vent holes...
That is a great idea. Let us know how the vent holes work. Our shopvac wasn’t very powerful but that would be a frustrating issue.
Worked great. I ended up cutting slots out of the foam all around the edge
If if sticks you have done it right.
John Jubei I noticed that some of the name brand models have vent slots on top
Thanks! Apparently millwaukee doesn't make a dust shroud for my angle grinder. Why would they do that?
I had the same problem. After realizing how much dust grinding concrete makes I couldn't find one for sale anywhere local. I guess necessity truly is the mother of innovation (AKA unnecessary duct tape utilization)
saved me £50
That is great to hear! It seems like everyone has at least one spare lid with no companion tub.
That grinding wheel (0:50) looks too big to fit with the guard (1:00) installed. Did you end up not using the guard?
That is a great question! I purchased a diamond grinder wheel one size up from what was supposed to be on my tool, I think 7 inches. The stock metal guard allowed the wheel to attach but did not cover the entire wheel. The beauty of it was that this allowed the plastic lid to mount to the metal shield and since the lid is bigger than the wheel, the lid extended past the wheel and the foam wrapped around the wheel with a air gap so there was no rubbing.
U.S duct tape . . Latin america hot glue pistol, ha ha ha
what model dewalt grinder do you have? I tried this with a angle grinder from harbor freight and the bolt the grinding wheel attaches to did not extend far enough to make this. tnx
It is the $100 Dewalt grinder, 11-Amp Corded 4-1/2 in. Small Angle Grinder.
How can we got it in bangladesh
I’m not sure. Can you order it online if you don’t have brick and mortar Home stores?
Just buy one at harbor freight.
you never show, how works.. "with attachment"/ "without attachment"
Ya, it was a TH-cam creator rookie mistake. There is another video we made about installing laminate floor that shows how well it works. In the other video you can see it work flawlessly until the shopvac filled up with concrete dust. I also show how much it collected when I unclog the shopvac.

Good idea.....you just can't demonstrate working in sandals! Come on man!!
Just buy one. There, problem solved.
